GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 290,245, dated December 18, 1883. Application filed July 23,1883. (X0 model.)

To all whom it may concern.-

Be it known that I, KUHLEMAN, of Laclede Station, St. Louis county, Missouri, have made a new and useful Improvement in Grain-Drills, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which Figure l is aplan, theseed-boxbeing removed, of a grain-drill having theimprovement; Fig. 2, a vertical longitudinal section on the line 2 2 of Fig. 1, and Fig. 3 a vertical longitudinal section on the line 3 3 of Fig. l.

The same letters of reference denote the same parts.

This improvement relates, mainly, to the mode of shifting the hoes.

A, Figs. 1, 2, represents a grain drill in which the improvement is embodied. Aside from its improved features the drill is of the customary form. A portion, B B, of the hoes, by means of their dragbars b b, are connected with a fixed part-say the cross-bar Cof the machine. The other hoes, B B, by means of their drag-bars Z) Z), are connected with the swinging bars D D-thatis, the hoes B at one side of the machine are connected with the bar D, and the hoes B at the other side of the machine are connected with the bar D. These bars D D are adapted to be moved forward and backward in the machine, to enable the hoes B B to be shifted into and out of line with the hoes B B. To this end the bars D D, by means of the arms (Z (Z, are, in dependently of each other, swung on the bearings d (1, respectively, upon the side bars, EF, and thetongue F. \Vhen the bars areswung forward, as the bar D, Fig. l, the hoes B B and the hoes B B are in line, and when the bars are swung backward, as the barD, Fig. 1, the hoes B B are out of line with the hoes B B. The swinging bars D D are held in their forward position by means of the stays G G, respect ively. These stays arejointed to the bars D D, respectively, and they are made to hold the bars in their forward position, as follows: A shoulder, upon the stay, is adapted, when the bar D or D is in its forward position, to come against afixed partpreferably the axle Hof the drilland in such position (shown in Fig. 2) the stay operates to brace the bar D or D and prevent it from swinging backward. To shift the hoes B B so as to be out of line with the hoes B B, the stay G is lifted sufficiently for the shoulder g to clear the axle, whereupon the swinging bar and hoes B B slip backward, as shown in Fig. 3. The stay has a suitable handle, g, which can be grasped by the operator, either from the drivers seat or from the rear of the machine, and the stay can be readily thrown up from the axle. The relative shape of the stay-shoulder g and the axle is also, preferably, such as to cause the stay of itself to jump upward from its bearing upon the axle whenever the hoes encounter an un usual obstacle calculated in case the hoes did not yield to occasion injury. A modification of this feature of the drill is reversing the stay that is, jointing it to the axle and letting the shoulder 9 come against the bar D or D.

After the hoes have been arranged to sow in two ranks, and it is desired to sow in one rank, the operator lifts the chain-bar and say, by giving one of the shifting hoes a kick-- moves the shifting hoes and swinging bar forward, whereupon the stay drops into place against the axle and braces the swinging bar in its forward position again. So far as this mode of securing the swinging bars is con eerned, these bars might be in one piece. It is preferable, however, to use two swinging bars and two sets of shifting hoes, as shown, as it is frequently desirable to shift the hoes on one side only of the drill. In accordance therewith the chain-bar is made in two parts, I and 1, corresponding to the two bars D D. By means of the chain-bar I, the hoes B belonging to the swinging bar D can be lifted, and by means of the chain-bar I, the hoes B belonging to the bar D can be lifted. The chain-bars, respectively, on the two sides of the drill, are j ournaled in bearings 2' 5, respectively, on the side bar, E, and thetongue F. The drill is preferably supplied with a roller, J, which is journaled in the brackets jj, that depend from the side bars, E E, in front of the hoes.

It will be noticed that thetongue F extends to the rear of the machine, and that, together with the side bars, E F, constitutes the main portion of 'the frame-work of the mach ne.

2 seams The frame-workis thus simplified and strength- I movement independent of the other bar and ened. seat K.

The chain-bars I I have handles 6" i by which the bars can be lifted. \Vhcn the bars are turned down, the handles serve as footrests for the occupant of the seat K. As these handles when turned down, as in Fig. 2, are liable to be in the way of the attendant in moving the hoes, they are connected with the bars I I in such manner as to enable them to swing forward, as indicated by the dotted lines, and thus be out of the way, or be no obstacle to the attendant. -The tongue may be braced, as indicated by the dotted lines ff, Fig. I.

I claim- 1. A grain-drill the shifting hoes of which can be shifted in sections which are independent of each other.

2. A grain-drill the shifting hoes of which, upon one side of the drill, can be shifted from a straight into a zigzag line independently of the hoes upon the other side of the drill.

3. The combination of the swinging bars D D, the staysG G, and the axle H, the bar and stay upon one side of the drill being in their The tongue also serves to support the stay, substantially as described.

4.. The combination of the hoes B B, the hoes B B, the bars I) b, the bars I) b, the bars 0 E E, the tongue F, the independent swinging bars D D, and the stays G G, substantially as described.

5. A grain-drill the shifting hoes of which are in sections, either one of which can be operated without operating the other, and which sections each are connected with a bar arranged crosswise and movable forward and backward in the drill, and, when in its forward position, held by a stay interposedbetween the bar and a fixed bearing in rear of the bar.

6. The combination of the hoes B B, the hoes B B, the bars D D, the stays G G, and the chain-bars I I, the hoes B, bar D, and chain-bar I at one side of the machine being in their operation independent of the hoes B, bar D, and chain-bar I at the other side of the machine, substantially as described.
